SPECIFICATION forming` part of Letters Patent No. 611,797, dated October 4, 1898. Application led November 1, 1897. Serial No.`657,088. (No model.)

To all whom it may concern: f

Beit known that I, LONGLEY LEWIS SAGEN- DORPH, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Metallic Ceiling or Tall Plates; and I do hereby declare the followin gto be af ull, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention has relation to sectional rnetallic ceiling and side-wall plates employed for finishing and decorating purposes in lieu of plaster, stucco, paper, dac., and has for its object the provision of a backing or lining to the plates, whereby, among other advantages, the ceilings and walls to which they are applied are rendered non-conductors of heat and cold and of noise and disturbing vibrations and whereby the accumulation of Incisture by condensation on the backs of the plates is prevented and all joints and seams rendered dust, water, and gas proof.

My invention consists in the application to or combination with the ceiling or wall plates having lapped or interlockedjoints and so constructed as to form panels or sections which are fitted together in various Ways, according to the conditions of use'and architectural design, of sheets of felt or other nonconducting material, forming a lining 0r backing between the metallic shell and the surface covered thereby and having the characteristies above referred to and hereinafter more specifically described.

My invention further consists in the combination, with the metallic plates having the felt backing or lining, as above set forth, of

wood edge-strips-suitably securedfto the metallic plates, as hereinafter described.

In the accompanying drawings, Figure l is a plan view of an ornamental sheet or panel l of metal constituting a section of a ceiling ory side-wall' covering and having applied thereto a non-conducting backing or lining according to my invention. Fig. 2 is a sectional view of the saine on the line X X of Fig. 1. Fig. 3 is a plan view of the plate shown in Figs. 1 and 2, with the addition of wooden edge-strips and Figs. 4 and 5, sectional views showing the wood strips applied to opposite sides of the plate;

The metal plates or sections A are rectangular and of -any desired ornamental configuration and of any proper mechanical structure as regards the marginal or joint parts, but are preferably of the type shown in the drawings, in which two adjacent sides have wide margins beaded, as at a, so as to form,

with the ornamental molding-beads b b of the two other sides, interlocking lap-joints.

It has been usual heretofore to attach the plates directly to the furring-strips without u'singanyintermediateliningorhlling. This has been found objectionable, and particularly so when the ceilings or walls themselves are not perfect non-conductors-of heat and cold or when they offer but little obstruction to noise or-'vibration To overcome these and other objections, I provide sheets of nonconducting material, such as roofing-felt, between thc sheets of metal and the furringstrips and arrange s uch non-conducting sheets in various ways to the different requirements or conditions of use.

As will be seen, the felt sheet B, which I employ for lining or backing purposes, while of approximately the same dimensions as the metal plate, is applied to the back of the latter, so as to project at its two edges l and 2 half an inch beyond the edges 3 and 4 of the metal plate, thus leaving uncovered about half an inch of metal on each of the two edges 5 and 6. The object of this arrangement is to allow of 'a perfect contact and lapping of the sheets of felt with each other after the -metal plates are lapped, while not interfering with the lapping of the metal on the metal. Thus when the plates are in position the metal surface of one plate is in 'joint contact with the metal surface of the one it overlaps, While underneath or back of these plates the sheets of felt overlap each other. f

The sheets of felt are preferably attached by liquid cement to the sheets of metal before being put up, and when the plates are stamped so 'as to Vpresent surface configuration the sheets of felt are pressed firmly into the recesses on the backs of the plates, so as to be in perfect contact with them and leave no open or air space between the felt and the metal.

The felt sheets, instead of being pressed into the recesses of the metal sheets and cemented thereto,may be pressed so as to have the same configuration and then loosely applied to the plates---t' e., without cementing. I prefer, however, to securely fasten each sheet of felt to its metal plate before shipping it from the factory', the felt-lined metallic sheets thus constituting a new article of manufacture ready for use and only requires to be putin place and nailed to the furringstrips.

In some cases I find it advantageous to attach strips of wood to the separate plates, such strips being arranged around the edges of the plates so as to form a border, such construction being shown in Figs. 3, 1, and 5 of the drawings. The strips are mitered at the corners and nailed together and to the metal plates, and when the plates are put in position on the ceiling nails are driven through the metal plates, the felt backing, and the Wooden strips and into the furring of the ceiling. In the sectional view Fig. 5 I have shown these wood en strips C as applied to the back of the metal plates and on the outside of the felt backing B. When applied in this position, nails D are driven through the metal plates A, the felt backing B, and the wooden strips C and into the furring-strips or other surface to which the plates are bein g secured when the plates are being put in position on the ceiling. The wooden strips are set back from the edge of the metal plates a sufficient distance to permit of the edge of the' plates overlapping on two sides, as hereinbefore described.

In Fig. 4 of the drawings I have shown the wooden strips C as applied to the outer metallic side of the ceiling-plate, thestrips being in such position that when two adjacent plates come together the edges of the wood strips of the adjacent plates abut, and when the plates are secured in position on the ceiling by nails passing through the wooden strips and the plates I place a cap E over both strips and nail the cap in position by nailspassing through the wood strips and into the furring-strips of the ceiling, and I then finish the corners with suitable rosettes.

Having thus described my invention, what I claim as new s I. The combination with rectangular ceiling or wall plates of the character described, having their edges or margins shaped to form lap edges or joints, of the non-conducting backing or lining sheets having their edges on two adjacent sides projecting or extending beyond the edges or margins of the plates and o`n the other two sides terminating back of, or inside, the edges of the plate, substantially as shown and described.

2. The combination with an ornamental ceiling or wall plate composed ot a sheet of metal having a felt or other .non-conducting backing of the wooden strips secured to the metal plate in proximity to the edges thereof, substantially as described.

In testimony whereof I have affixed my signature in presence of two witnesses.
